【Abstract】 By using the internal resources of the sensor DS18X20, this paper replaces the 48-bit of digital serial number by BCD code, and introduces a practical technique to simplify the address encoding in multi-point temperature detecting system. To cope with the possibility of addressing code lost, a feasible solution was proposed to do the online debugging during system maintains.更多还原
